DAMPER.

SPECIFICATION forming part of Letters Patent No. 323,37, dated uly 28, 1885. Application tiled November 10, 1884. (No model.)

To all whom it may concern Be it known that I, Josnrn P. TUTTLE, of Onondaga Valley, in the county of Onondaga and State of New York, have invented certain new and useful improvements in Dampers; and I do hereby declare that the following is a full, clear, and exact description thereof, rei`- erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form partof this specification, in which- Figure l is a top view of my improved lluepipe and damper. Fig. 2 is a vertical section through the pipe and damper in the plane indicated by dotted line m on Fig. l. Fig. 3 is a vertical section taken through Fig. l in the plane y y. Fig. 4 is a bottom view of the damper.

This invention relates in part to an im provenient on dempers for dues, for which United States Letters Patent were granted to me bearing date on the Sth day of March, 1870; and the nature of my present invention consists, first, in a damper composed of two parts in different planes, having concave and convex edges, which parts are readily detachable, but firmly connected together by the spindle of the damper; second, in combining with my improved damper a stove pipe composed of two vertical sections united by means of beads and embracing grooved ilanges therefor, all of which will be fully understood from the following description, when taken in connection with the annexed drawings.

A A designate the two vertical parts which compose my improved short stove-pipe section. The lower end or sleeve of the pipesection is elliptical, and the upper part is cylindrical, united together by a horizontal seam and constructed with upwardly-converging portions A2 A2. I thus adapt a cylindrical pipe to tit an elliptical collar of a stove. The two vertical parts A A are detachable by endwise movement, and they are connected together by means of round beads (t a, tted closely into concave flanges b b. Said parts can thus be readily separated and put together whenever desired, and no other fastenings than those described are required.

The damper, which is of the oscillating and rotating kind, is composed of three detachable sections-namely, the bottom section, C, the top section, D, and the spindle E.

The bottoni section is composed of two flat ovate` plates, c c, united by angular bridges d d, having tenons e con their upper ends and cast with the plates c c. These plates c c have external and internal convex edges, and the plates are separated to leave a space between them, which diverges laterally from the center of the damper, as shown in Fig. 4.

The top plate or section, D, is constructed with concave or scalloped edges e e and broad convex ends, which latter coincide with the inside of the luepipe. This top plate is constructed with holes ff, adapted to receive freely the tenons c e on the angular bridges d d, and it is also constructed with a central lug, g, having an angular passage through it. The bridges d d are directed upward, and the perforated lug g is directed downward, so that when the plates are adjusted together by inserting the tenons e c into the holes ff these plates can be securely united by passing the square shank of the spindle E through the bridges d d and lug g.

The spindle E has its end bearings in the sides of the due-pipe, and at the junction of the handle E', with the shank a disk, E, is formed on it, which, with a pin or ring, It, passed through its opposite end, prevents a casual detachment of the spindle from the damper and pipe. The disk is constructed with a pointed pin, t, on its inner side, which is designed to enter either one of several holes made in the pipe and to hold the damper in any desired position. The spindle is allowed endwise adjustment, by which the pin z" can be adjusted in the holes provided for it, as described.

I am aware that damper-rods have been made to lock, and that damper-plates have been made in two parts, held together by the substantially as and for the purposes dedamper-spiudle, and I do not claim such, scribed. broadly; but, In testimony that I claim the foregoing as Having described my invention7 I claimmy own I aiix my signature in presence of 5 A damper composed of two ovate bottom two witnesses.
